Bad, bad bad bad - Vector Optics Ultra Low Profile Offset Picatinny Rail Mount

Terrible, flimsy and soft, no usable threading, just bad all around. The material is too soft to retain thread engagement with the screw which itself is too short and freely flops around. The rail on its own appears a bit too narrow for most accessory attachment types, leaving them loose and wiggly. Not terribly expensive so no big loss, but still disappointing.
